At first I thought it was a plane heading towards Allegheny County airport to land; but then I saw an airplane in the vicinty and realized that it could not have been a plane. It was much brighter and larger than any plane's lights I have ever seen. Check with Allegheny county airport for potential reports confirming my observation.
